Furthest north in the island community Rongevær, at the entrance to Fensfjorden, lies Krossøy. Belonging to the farm are the islands of Krossøy, Husøy, Kårøy, Lyngkjerringa, Søre Kjerringa, Rotøy and Kuhovet. All of them have been inhabited. On Krossøy itself today there are four holdings. The marine use environment here is one of the best preserved along the West Norwegian coast.
The farmhouses at holding No. 15 at Hopland are built together to form a long, continuous building, with dwelling house, hayshed and cowshed built in one row. There have been many such joined structures in the coastal communities, but today there are few remaining. If we travel to the other side of the North Sea, to the Faeroes, Shetland and the Orkney Islands, we find corresponding features in the older building traditions. We find ourselves in a large North Atlantic cultural area.
